Aloha! You're speaking to Dr. Michael Salkin
The little pimple-like sores indicate pustules of a superficial spreading pyoderma - a bacterial (Staphylococcus, usually) skin infection. Pit bulls appear to be overrepresented with this type of infection when compared to other breeds. A systemic antibiotic in the cephalosporin class such as the prescription cephalexin prescribed for a minimum of 3-4 weeks and 1 week past clinical signs should be helpful and bathing Nitro in a chlorhexidine- or benzoyl peroxide-containing shampoo should hasten remission. These shampoos are available over the counter and at Nitro's vet's hospital.
It would be prudent to perform skin scrapings once again. It's not unusual to have falsely negative skin scrapings when the demodectic mange mite is present. Those pustules are also seen secondary to such a mite infection.

Thank you! Yes, this represents a superficial spreading pyoderma. A minimum of 3-4 weeks of cephalexin plus 1 week past clinical signs will be necessary. If you didn't see a positive change within the first two weeks, repeat skin scrapings should be made.
Please continue our conversation if you wish.

Went to vet today. Had skin tests? No mange or mites. Gave him cefalexin and prednisone. Also flea med. bringing him back 2 weeks to see if infection in his right ear. Meds for that too. Thanks.

Thank you for the update. I'm not thrilled with the use of prednisone when skin infection is present. Is Nitro so pruritic (itchy) that he needs prednisone? What does Nitro weigh and what dose of prednisone was prescribed, please?
